Well I can answer more questions on effects this substance does. I found out that the reason for the psychedelic effects I got is beacuse I tried a low dose of Methedrone (not Mephedrone) some hours before taking this substance. bK-DMBDB acted as a MAOI with Methedrone. Alone, bK-DMBDB does produce little stim but not enough to make it interesting to try more.

It actually does. But this is like the gazillionth betaketon variant of a substance. For me, from methylone and butylone it all became less and less interesting. All more or less same effects, all stimulants. Some with the nice empathogenic taste but really... Tasting Ethylone was for me the reason to stop pursuing these compounds as the most interesting have seemingly been found.
